Hey @yevgenii,
Thanks for reaching out!
It seems you are looking for a plugin that allows you to add custom checkout fields, as well as change the standard checkout fields, correct?
The Checkout Field Editor extension can help you achieve this. As the extension documentation mentions, this extension provides you with an interface to?add, edit, and remove fields shown on your WooCommerce checkout?page.?
Fields can be added and removed from the billing and shipping sections, as well as inserted after these sections next to the standard ‘order notes’. Core fields can also be moved around giving you?more control over your checkout without touching the code.
WooCommerce.com offers a 30-day refund policy which you can take advantage of, allowing you to test the extension, and make sure that it suits your needs.
Should you have any pre-sales-related questions, kindly contact us directly at?WooCommerce.com → My Account → Support. You will need to create an account if you do not have one already.
Hope this helps!
